SCMT 120404 T9225 ISO turning insert — Tungaloy (CVD‑coated carbide, 0.4 mm radius)

The SCMT120404 T9225 is an ISO‑indexable turning insert engineered for medium to heavy steel turning, offering a robust, CVD‑coated carbide grade and a 0.4 mm nose radius for adaptable surface finish.

• Universal CVD‑coated carbide grade T9225
• 0.4 mm nose radius for adaptable finishes
• 7° relief angle for stable cutting
• Square insert, 12 mm size, 4.76 mm thick
• Cylindrical hole with single‑side countersink

High productivity for medium to heavy steel turning

The CVD‑coated carbide grade T9225 combines toughness and wear resistance to maintain cutting performance under varying engagement conditions. As a universal grade, it is suited to mixed batch work and operations where occasional interrupted cuts occur. The coating increases surface hardness and reduces flank wear, which means fewer tool changes and improved uptime on the shop floor. Production planners will appreciate the balance between tool life and cutting reliability when machining medium to heavy steel components.

Consistent chip control and finish with minimal setup changes

Chip flow and surface quality are governed by the insert geometry: the one‑sided chipbreaker and 0.4 mm nose radius guide chip evacuation and influence the final finish. A modest nose radius supports both dimensional control and acceptable surface texture without demanding excessive cutting forces. The 7° relief angle gives a stable cutting edge engagement that reduces rubbing and heat build‑up, prolonging the life of the insert under mixed cutting conditions. For non‑specialists: the chipbreaker reshapes chips to prevent tangling and improve coolant access, reducing machine interruptions.

Seamless integration into ISO holder systems

Compatibility is secured when an insert is matched to a holder by key parameters: form, relief angle, tolerance class, fastening, size and thickness. The insert is a square profile with a nominal 12 mm size and 4.76 mm thickness, and features a cylindrical hole with single‑side countersink (40°–60°) to ensure secure clamping and repeatable positioning. Typical system components include an ISO indexable external holder or a boring bar, plus a suitable backing plate or clamp set and replacement screws for maintenance. Correct matching reduces vibration and improves surface quality without additional complex adjustments.

Material and grade explained for confident tooling decisions

The CVD coating on this carbide substrate enhances wear resistance and edge stability, supporting longer runs and consistent dimensional accuracy. The grade’s design promotes stable chip formation and robust edge behaviour during light interruptions or variable feeds — factors that reduce scrap and machining cost per part. Brand reliability is another consideration: Tungaloy’s production standards and grade development target predictable performance in workshop environments. If cutting data or feed/speed recommendations are required, technical assistance is available to help integrate the insert into existing processes.

FAQ

What materials is this insert suitable for?
The SCMT120404 T9225 is designed primarily for medium to heavy steel turning and provides reliable performance on a variety of steels where toughness and wear resistance are required.

How does the T9225 grade affect tool life?
The CVD‑coated T9225 grade increases surface hardness and improves wear resistance, which typically extends insert life and reduces the frequency of tool changes in standard turning operations.

Which holder features are required for compatibility?
Compatibility depends on holder form, relief angle, tolerance class, fastening, size and thickness; the insert’s square 12 mm profile and 4.76 mm thickness must match the chosen ISO holder or boring bar.

Is the insert suitable for interrupted cuts?
Yes — the robust universal grade and carbide substrate of the SCMT120404 T9225 are intended to tolerate occasional interruptions and variable engagement conditions.

What does the chipbreaker do and why is it important?
The one‑sided chipbreaker reshapes and controls chip flow to prevent tangling, improve coolant access and reduce machine downtime, enhancing process stability with this insert.
